I just replaced my tank after having it off to find there is a fuel leak at one of the quick release fuel line connectors!

I have inspected both the fuel lines ends, and the connectors in the tank and can't find any signs at all of damage or broken seals at all etc.

I was really careful when disconnecting them so I am not sure what is going on, as I said it is only ONE connector that is leaking and the leak becomes a small river when I turned the fuel pump on....

please help.......

Plastic connectors ?

Have you swapped the plastic for the metal fittings yet ? If not then I will bet it is the 90deg fittings which are either cracked or broken.
Read through this and then contact CAG for fuel fittings.

Cheers Donsy,

That is an amazing thread you have pieced together and really well documented.

I may well end up replacing the fittings to the metal version, but I am still wondering what is going on as I can't for the life of me spot any damage or cracks or anything so I wouldn't want to replace the parts if they are not broken.

It appears as if the leaking connector is not engaging properly but it does have a nice sharp click as I push it into position and the seal is sliding in fine.....

Thanks heaps for the link to the thread mate, awesome work.

Will.

No problem Will, what are the o-rings like on the 90deg fittings, i have piched them b4 and then fuel just pisses out. BTW, in time get some of the metal fittings, even if you just get the 90deg one's, because those plastic one's will fail for sure.

I've had to move my tank on and off a good few times in the last couple of weeks. What I can say is that if plastic fuel connectors were fitted...they would definitely have broken as they aren't up to the job. The flexible fuel lines aren't that flexible..and the area under the tank is cramped and full of snags..so the 90deg plastic connectors get tugged and pulled. As they age they get brittle and "work hardened" and they snap. For what it costs change them as the thought of fuel leaking out onto a hot engine or in your garage at night doesn't bear thinking about...As an illustration ..would you want plastic handle bars ?

It's a no brainer..change them for peace of mind...

Hey Donsy guess what, turns out the O-ring seal in the 90 degree connector had a tiny nik in it.

Everything else is fine, as I had already bought the metal connectors for the tank and the fuel line I just used the seal from the new connector and will do the full replacment once I have all the other bits, I have a few other bits and bobs to take care of first and I'm keen to get her back on the road asap after replacing the stock air filter with the BMC job and keen to check the difference.


Thanks heaps for the tip mate.
